remote access concentrator

A remote access server that supports one or more T1/E1 lines, allowing multiple analog and ISDN calls to come in over one port from the telephone company. Remote access concentrators can handle much higher call densities than remote access servers. They include the dial-up protocols, access control and the equivalent of a modem pool. See remote access server, remote access router and IAD.
